Integrated municipal sludge destruction and resource recovery technologies

该提案旨在将UBC开发的前沿技术整合到安纳西斯研究中心（ARC）的高效污水污泥处理系统中，用于污泥固体破坏和生物能源回收。安纳西斯研究中心是位于三角洲的安纳西斯岛污水处理厂附近的最先进的污水研究设施。集成系统由UBC专利的微波增强高级氧化工艺（MW-AOP）和创新的厌氧消化（AD）系统组成，用于甲烷生产。微波废水处理系统不仅可以降低污泥固体含量，而且可以促进营养物向溶液中的释放。所得到的溶液将使微生物容易完成生物降解，从而提高沼气产量。此外，通过创新的厌氧消化系统可以实现更高效的生物能源生产。本次研发项目需要完成的任务包括：1)ubc设计的中试规模连续流微波处理系统的测试；2)检验两相厌氧消化系统的性能；3).首先在ARC评估综合系统的性能，然后在大温哥华地区的一个污水处理厂进行评估；4)建立了该集成系统的设计准则和操作规程。该项目的最终成果将是一个全面发展的“概念验证”综合污水污泥处理系统。该项目开发的废物管理、污泥减量和资源回收系统将对污泥管理和生物能源生产产生重大影响，并为废水处理行业带来可观的经济和环境效益。

This proposal aims to integrate UBC developed leading edge technologies into an efficient sewage sludge treatment system for sludge solids destruction and bioenergy recovery at the Annacis Research Centre (ARC), a state-of-the-art wastewater research facility adjacent to the Annacis Island wastewater treatment plant in Delta, B.C. The integrated system consists of a UBC patented microwave enhanced advanced oxidation process (MW-AOP) and an innovative anaerobic digestion (AD) system for methane production. The microwave wastewater system would not only reduce sludge solids content, but also facilitate the release of nutrients into solution. The resulting solution would make it easy for microorganisms to complete biodegradation, resulting in an increase of biogas production rate. Further, more efficient bioenergy production can be achieved by an innovative anaerobic digestion system. The tasks required in this R&D project include: 1). testing of the UBC-designed pilot-scale continuous flow microwave treatment system; 2). examining the performance of a two-phase anaerobic digestion system; 3). evaluating the performance of the integrated system at ARC first, then in one of Metro Vancouver's wastewater treatment plants; and 4). establishing the design criteria and operating protocols for this integrated system. The final outcome of the project will be a fully developed 'proof-of-concept' integrated sewage sludge treatment system. The improved waste management, sludge reduction and resource recovery system developed in this project will have a significant impact on sludge management and bioenergy production, and substantial economical and environmental benefits for the wastewater treatment industry.
